' CAR-BRAKE.

I Specification of Letters Patent.

Patented July 21, 1908.

Application filed. November 29, 1907. Serial No. 404,439.

'car, by mechanism actuated by this accidental separation of the carfrom others preceding it in a train. The brake eifectis produced bycausing a chain attached to the brake beam, to be wound upon an axle onthe car truck.

In my application for a patent for a ,pipe coupling, of even dateherewith, I use a reciprocating, twisted plate, which is caused to moveat the instant of the detachment of a car, and to' this twisted plate,as actuating means, I connect :the mechanism of'thisdevice. But any,other means may be employed. Ialso connect this device with the handbrake, so that-it may be controlled by the brakeman. p

The accompanying drawing illustrates the device, in which y Figure 1 isa side elevation of the device, suspended to the under side of a car,awheel of the car truck being removed to better expose the mechanism.Fig. 2'is afragmentary end elevation of the device, Fig. 3 IS afragmentary plan view of the same, the car body bein removed; and Fig. 4isan end view of a ban constituting one member of a clutch employed.

7 The character 8 designates the bottom of a car. v i

" 9 and 10 are hangers connected to the car bottom and supporting partsof my device.

11, '11, 'are tnetruok-wheels, and 12 is the axle connectin thesewheels.

15 is the en of the reciprocating plate referred to inthe statementabove, and 14 is a rod connecting said plate with the bell lever 13,which moves the band 18 On the axle 12, I place this band 18, whichconstitutes one member of a clutch. 'Said member s movable,longitudinally on, said axle, and has a groove 19, to engage a key 20,on the axle, and thus is made to revolve with said axle. 26 is the othermember of the clutch having a lug 27 to engage lug 24, on band 18. It isalso providedwith a groove 28, for a chain 29, to be connected with abrake beam,

and a'groove '30 which engages a pin'31 on the lever 32, the latterbeing connected by chain 35 through the bell lever 36, with the chainwheel 38 on the pinion 39, controlled by the brakeman through hand wheel40. A contractile spring 25 connecting lever 32 with hanger'9, restoresband wheel 26 to its normal position, when moved therefrom by thebrakeman. This device becomes 0 erative whenthe movement of plate 15 anrod 14 throws clutch member 18 into engagement with member'26, wherebythe chain 29, is

wound upon member 26, andthe brakes are forced a ainst. the wheels.

What claim and desire to secure is- I 1. A car brake comprising a caraxle, a clutch on said axle whose member 18 rotates with said axle andis also movable longitudinally on said axle, a clutch member .26 looseon said axle and engageable by said member 18, a chain on said clutchmember 26 connecting with the brake beam and means tothrow said clutchmember into engagement with said member 26, as specified.

2. A car brake" com rising hangers beneath the car, a car ax e, a clutchon said axlewhose member 18 is keyed to said axle and is longitudinallymovable thereon, and has an annular groove therein, a bell lever whosepoint engages said groove and is connected with the actuating means,clutch member 26 having an annular groove, a lever 32 whose pointengages said roove, said lever 32 havin connection wit a brake staff andhand w eel, a contractile spring connectin said lever 32 to a hanger anda chain on sai clutch member 26 to connect with the brake beam, asherein set forth.

In testimony whereof I affix my signature,

. in presence of two witnesses.
